A few more quotes come to mind:
"Good things come in small packages."
"It is the little things in life that matter."
How many times do we stop and smile during the day at the little things that make us happy?
My three and a half year old daughter loves to paint and draw and has recently developed what I will call her "signature trademark".
The smiley face in the picture above.
I can't tell you how happy it makes me to see it.
